Advantages

  • Voltage output signal
  • Possibility of embedding a temperature sensor
  • It works together with the H5850 device or independently
  • Small size and convenience in portable operation
  • Quick connection with coupling
  • High degree of protection
  • Possibility to prepare samples of the material

Description

The RHP is designed to convert the moisture content of bulk materials into a standardized voltage output signal. The probe is specially adapted for quick measurement in a set with a portable moisture meter model H5850 of COMECO, but it can also be used with other portable devices with a programmable or adjustable input. Using
based on the principle of changing the dielectric constant of the material by the moisture content, the RHP converts the capacitance of the material placed in the cell into an electrical signal that changes in proportion to the change of moisture in the material. Moreover, a platinum temperature sensor can be built into the probe to measure the temperature of the environment simultaneously with the humidity.
